HOT-AIR REGISTER.

Specification of Letters Patent.

Patented July 2, 1918.

Application filed September 1, 1917. Serial No. 189,240.

To all whom it may concern: 0

Be it known that I, ELLIS L. HAYDEN, c1t1- zen of the United States, residing at Warrcn, in the county of Trumbull and State of Ohio, have invented certain new and useful Improvements in Hot-Air Reglsters, of which the following is a specification.

My improvement relates to wall registers and comprises a new and novel arrangement of parts substantially as herein shown and described and more particularly pointed out in the claims.

The object of the invention is to provide a hot air register adapted to be used w th hot air systems for heating houses and which register is particularly constructed to fit into the wall of the house, preferably at the floor line and base board of the wall. In such registers it is desirable to have ample pa ssage for the discharge of the heated air while also guarding against the admission of any foreign matter or objects into the hot air pipes, and the screen or guard used must be constructed accordingly and should be strong and durable, as well as decorative in view of the fact that such registers are constantly visible. In addition, the cost of production of such registers must'be low. My register is designed to meet all such require-- ments, being of simple construction, and exceptionally strong and having a neat and attractive appearance.

In the accompanying'drawings, Figure 1 is a front View of my improved hot air register with a portion of the open-meshed screen broken away to disclose the frame and damper plate.

Fig. 2 is a cross-section of the register on line 22 Fig. 1.

Fig. 3 is a vertical section of the register on line 33 Fig. 1.

Fig. 4 and Fig. 5 show a front view and section respectively, of the screen or guard, the view being somewhat large as compared with Fig. 1.

Fig. 6 is a rear view, or a corner of the register, showing the clamping bearing or the pivot rod of the damper plate.

The register comprises a stamped sheet metal body 2, which is adapted to be affixed within a suitable opening at the base of a wall or partition in a house having hot air circulating pipes. This frame has a rectangular opening in its face, which is bordered by a slight depression 3 adapted to form a seat for the metal frame 4 of a guard or screen 5, which spans and covers the rectangular opening in the body. Suitable screws 6 secure the guard or screen 4 to body 2 and angle members 7 are fastened to the inside face of the body on all sides of the opening, and a damper plate 8 having a pivot rod 9 is suspended at the rear of the screen within the space defined by the projecting angle'pieces 7. Pivot rod 9 is frictionally clamped in place by bearing plates 10 and screws 11, the heads of the screws being covered by the angle frame 4 of the guard, see dotted lines, Fig. 1. Thus, in order to tighten the friction plate 10 upon pivot rod 9 or if the damper plate is to be removed, it is first necessary to remove the guard. The body 2 has a slot at one side through which bent end 12 of pivot rod 9 is projected to permit damper plate to be operated back and forth relatively to the screen. In a full sized device the screen or guard covers a fairly large opening, and in order that the screens have the necessary rigidity plus a large number of openings for the passage of the heated air, I prefer to employ a separate sheet of metal 14 which has been cut and stretched to provide a multiplicity of diamond shaped openings with the connecting webs 15 between the openings bent to for 1 rigid stays front to rear of the screen or guard. Each web 15 is relatively thin but offers substantial resistance to pressure from the front side of the register because the fiat face of each web is disposed or lies in a plane transversely of the register and with its edges facing the front and rear sides of the register- This open meshed material 14 is electrically welded upon the inner face of the metal frame 4 but may be secured therein in any other suitable way.

What I claim is:

1. In hot air registers, a sheet metal body having a rectangular opening and an inwardly-projecting flange about its outside, a screen and a flanged frame providing a seat therefor mounted on the outside of said body, angle pieces on the inside of the body about the opening therein and screws secur-- ing said frame and the said angle pieces to the body.

2. A hot air register, comprising a body having a pivot damper plate, and a separate screen removably aflixed to the front of said body opposite the front of said plate, said damper plate having a pivot rod and said body having clamping plates affixed to the rear side thereof forming pivot bearings for sald rod; and clamp screws for said plates extending through said body having screw heads covered and inclosed by said movable screens. 10
